Open Laps After Freeze And Thaw
Seam adhesive and tape lose grip after months of freezing nights and warmer afternoons.
Lapped seams are cleaned, primed, and covered with new seam tape or a heat-welded strip that holds through summer heat.
As a Niantic commercial roof repair contractor, we fix winter damage on shop and storefront roofs in spring, before seasonal business picks up.


Niantic commercial roof repair often starts in March or April, when a shop owner reopens after a quiet winter and finds a stain over the counter or water near a back door. Freeze and thaw cycles open seams, lift flashing, and crack sealant while the building sits half empty.
We walk the roof early, mark every opening winter left behind, and repair it while the weather is mild and the parking lot is still quiet. The aim is a dry roof before customers and summer storms arrive.
These are the roof conditions seasonal owners tend to find when they reopen. Each one points to a part of the roof we check and repair first.
Melting snow ran into an open lap or a split at a pipe boot and followed the deck before dripping through the ceiling.
We trace the stain back uphill, open the wet area, replace soaked insulation, and patch the membrane with matching material.
Ice and debris crushed insulation near a drain, or the drain strainer clogged, so water sits in a low spot for days.
Crews clear the drain, reset the clamping ring, and build up the low area with tapered insulation under new membrane.
Winter wind worked the fasteners in the edge metal and coping loose, and the joints between sections pulled apart.
We refasten or replace the edge metal, seal the joints, and strip in the membrane so wind has nothing to catch along the edge.
Sealant hardens and shrinks in cold weather, so the beads around vents, curbs, and pipe flashings split and let water in.
Old sealant is cut out, the surface is cleaned, and new flashing or pitch pans go around each penetration.
Spring repairs fix the parts winter wore down, so the roof goes into the busy months with closed seams and tight metal.
Seam adhesive and tape lose grip after months of freezing nights and warmer afternoons.
Lapped seams are cleaned, primed, and covered with new seam tape or a heat-welded strip that holds through summer heat.
Leaves, sand, and grit collect in drains and scuppers over the off season while nobody is watching the roof.
Clearing the drain and adding a new strainer lets heavy summer rain leave the roof instead of backing up under flashing.
Base flashing along walls and parapets cracks where it bends, especially on older storefront roofs.
New base flashing and counterflashing go in at the wall, so wind-driven rain stays out of the joint.
Service techs crossing the roof to rooftop units scuff and puncture the membrane along the same path every visit.
Punctures get patched and walkway pads go down along that path, so summer service calls stop wearing the roof thin.
Four repair services cover the roofs on shops, storage buildings, and light industrial properties around Niantic.

Flat roofs on storefronts collect winter grit at drains and open seams in the cold. Flat roof repair clears drains, patches seams, and fixes low spots before summer storms.
Flat Roof Repair details
Metal storage and shop buildings lose fastener washers and end lap sealant over winter. We replace failed screws, reseal laps, and swap any panel rusted through.
Commercial Metal Roof Repair details
When a stain shows up on reopening day, leak repair traces the water from the ceiling back to the seam, flashing, or penetration letting it in.
Commercial Roof Leak Repair details
Light industrial roofs carry fans, vents, and equipment curbs whose flashing cracks in the cold. Industrial roof repair reflashes curbs and fixes membrane around exhaust.
Industrial Roof Repair details
Call and tell us where the water showed up, what the weather did that week, and whether the roof is membrane or metal.
A spring repair visit follows four steps, from the first roof walk to a dry check after the next rain.
Early in spring we walk the whole roof and mark open seams, loose edge metal, packed drains, and cracked sealant, with photos for the owner.
Each problem goes on a short list ranked by how much water it can let in, so the worst seam or drain gets fixed first.
Crews patch membrane, reflash curbs, reset drains, and refasten metal in the weeks before the business opens for the season.
After the next heavy rain, the repaired areas and the ceiling below get a second look to confirm the leak path is closed.
We take commercial roof repair work in fourteen towns near Niantic, plus Groton. Building somewhere else? Call us or send us a message and ask.

Repair Cost
The size of the damaged area and how much wet insulation sits under it drive the price most. Drain work, the number of curbs and walls that need new flashing, roof height, and access for ladders or a lift also change it. We price each repair after walking the roof and checking for moisture.
Seasonal Timing
Plan the roof walk as soon as the snow is gone and the surface is dry, which leaves time to repair before opening. Membrane adhesives and sealants need mild temperatures to bond, so work goes faster once nights stay above freezing. Booking early keeps repairs out of your busiest weeks.
Local Businesses
Most visits cover seams, flashing at walls and curbs, drains, and edge metal on shop, storage, and light industrial roofs. We patch membrane, replace fasteners on metal roofs, and reflash penetrations. Larger wet areas get cut out and rebuilt with new insulation so the repair matches the existing roof.
Winter Damage
Yes. A seam that opened in January can stay dry through light spring showers and then leak in the first hard summer downpour. Moisture readings and core cuts during a spring inspection show wet insulation before it reaches the ceiling, so the repair happens on your schedule.
Permits
Ask the local building official, since that office decides whether a repair needs a permit. Connecticut building work follows the 2022 Connecticut State Building Code. Before larger membrane, insulation, or deck replacement begins, we confirm what the office requires and plan the spring work schedule around it.
